The role of urea in the oviposition behaviour of Japanese encephalitis vectors in rice fields of South India

Memorias do Instituto Oswaldo Cruz, 2003
The effect of urea on the oviposition behaviour of culicine vectors of Japanese encephalitis was studied in rice fields. Gravid females had a strong preference for oviposition in urea treated areas in rice fields, while no such preference was exhibited ...

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region

Pest Management Science, EarlyView.
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Variation of the Oviposition Preferences of Aedes aegypti in Function of Substratum and Humidity

Memorias do Instituto Oswaldo Cruz, 2002
Two Aedes aegypti (L.) populations were studied in the laboratory regarding the preference for three types of breeding sites, i.e., flasks containing only water, flasks with a plant and flasks with a stick.

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, EarlyView.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Optimal control and multitrophic physiologically‐based models: The binomial for successful decision support systems in insect pest management

Pest Management Science, EarlyView.
Decision‐making in integrated pest management (IPM) corresponds to an optimisation problem where the plant–pest dynamics and the control actions are constraints and where the objective function accounts for the costs of the treatments and the total income at the harvest time.

Predator egg‐induced non‐consumptive effects suppress spider mite survival and reproductive performance

Pest Management Science, EarlyView.
Increasing predation intensity of predatory mite significantly reduced spider mite fitness in terms of shorter mother longevity, lower mother fecundity, longer offspring development, lower offspring survival, and lower population growth. Abstract BACKGROUND Predators suppress pest populations not only through direct consumption but also via non ...

Effects of Geraniol on Survival, Reproduction, Endophytes, and Transcriptome of Tea Green Leafhoppers (Empoasca onukii)

Agronomy
Herbivore-induced plant volatiles (HIPVs) serve as powerful defense mechanisms that help plants mitigate pest-induced stress. Geraniol is a HIPV released by tea leaves in response to damage inflicted by tea green leafhoppers.

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Life Table Parameters and Digestive Enzyme Activity of Araecerus fasciculatus (Coleoptera: Anthribidae) Feeding on Different Stored Products

Insects
Araecerus fasciculatus (De Geer, 1775) is an important stored-product pest worldwide. In this study, the development time, survival rate, oviposition, and digestive enzyme (α-amylase, cellulase, pepsin, and lipase) activities of A.
